CONSTRUCTION IEEMBER.

Patented Aug. 10, 1909.

Application filed October 9, 1906. Serial No. 838,167.

To all whomit may concern:

Be it knowrrthat I, EDEN). PEI-iron, a citizen-of the United States residing in the city and eountypf San Francisco and State of have invented new and; useful Improvements in E'onstruction Memhers, of which the following is a specification.

My invention has for its OlI-jECt to produce ametallic construction mem-r er adapted to be usedin many situations inbuildings, as for instance as l. cams, joists, sills, the like; and also used for other purposes, as for instance fence posts.

It consists of a com-pound metallic construction memher embodying featuresthat will be hereinafter set forth.

In the accompanying drawings Figure 1: is a perspective view of a piece of material employed in making the improved construccut or slitted whichserve tounite the two-liars. Fig. 4 isa plan or face tion memt. er. 'Fig. 5-is taken on the line 5, 5 of 9 is a cross-sectional tion mem er iefore the first steps of operation thereupon are performed. Fig. 2 is a perspective view of the piece of material shown in Fig. r after it hast een formed into a channelfl ar. Fig. 3reprcsents two of the channel fare of Fig. l p-laced together and to form the flaps or tongues view of a completed construca cross-sectional view Fig. 4. Fig; 6 is an edge view. Fig. 7 is a view of a form of the invention with a feature added thereto that is not shown in Fig. 4. Fig. 8 is a longitudinal sectional view on the line 8, 8 of Fig. 7 I Fig. viewon the line 9, -9 of Fig. 7. Fig. 10 illustrates a composite construction mem'l'; er embodying features of my invention. Fig.11 is a perspective view of the ribhon form of anchor or'tying device shown in Figs. 7 to 10;,

In the drawings, A (Fig. 1 re resentsa plate or narrow piece of sheet meta of the desired .size to form one part .or section of a composite construction first step in the manufacture is 'to form the plate A into a channel bar, as represented in a 2, ha flanges grieind the upturned side edges or the main web portion a;

represented in this view the web part of the channel" b afis longitudinally corrugated for Z purpose that will he hereinafter described.

gether web to web asrepresented in Fig. 3,

when by suitable machinery or tools the web lintels and lement like; that representedveither in Figs- 4, 7 or 110' Thepair of these channel bars are placed tolongitudinally,

through, asindicated at b, forming flaps or tongues c, each attached by one edge to the web part of a ar lhe particular shape of the flaps or tongues and the form of the slits which produce them is not material. The next step in the-process of manufacture is to fold or tend hack the two superiinposer-l tongues or flaps against the outer face of one pf the well portions of one of the channel :ars; tures (1, and securely unites the two bars, thereby forming a compound metal bar or meml" er, such as represented in Fig. 4. This memi'cr comprises the two channel bars placed *0 ask to h ack or web to weh, united by folded-over flaps 0 arranged at the edges of openings 11 throughthe we?) of the memher H considered as a Whole. And in the preferred form of the invention the web part of the meml: er ,is longitudinally corrugated. This latter feature, however, is not essential in every emhodiment of my invention. As already stated, a construction member having the features described may be used for many purposes, being particularly adapted for use in buildings, especially those formed of metal and concrete. It possesses a number of distinct advantages, some of which I will set forth. It possesses great strength for the amount of material embodied. For fire protection and-other purposes it is desirable to cover and protect the metallic construction member wherever used in a building by fiferesisting material, such as plaster or concrete, and the apertures d are of advantage in that they ermit the masses of concrete or plaster on t e opposite sides of the web to be united by keys of such material passing through these apertures. Another advantage is that a member such as describedis well adapted to receive and hold .a nail,

This results in the formation of aper staple or bolt which may be driven into the edge of the member, at the joint'where the two parts thereof come together.

I am aware that I am not the first to provide a metallic construction member made of. two parts ada ted to have driven between them a nail, but, have discovered that when the web portions 'of the two parts of the compound member are (plane there is liabilityof the nail bein 'hel insecurely. gating the we portions of the channel bars shown, the difficulty of inserting a nail into the ed e of a member is not materially increase but the'grip of the member upon the have described and.

By corruagainst the webthereof.

the metal of the band or ribbon will usually.

nail is rendered certain and sufficiently .powerful to meet all demands. This enables me to easily-secure lathing, wire, rods or other objects to the edge of the member by nails or sta Ice, and to insure that each nail or staple s all have a secure engagement W1t the member into the edge of which it is riven.

In the form of the invention illustrated in Figs. 7 to 10, I have introduced a feature of construction in order to insure a more intimate union of the metallic member and the incasing masses of concrete or plaster which may be applied thereto. In the manufacture of this form of my invention I employ "a corrugated band or ribbon of metal, such as illustrated in Fig. 11, and piply it to the finished element represented in ig. 4.

rlbbon is represented by E and has the cor-- rugations or bends e. I- take a piece of the corrugated ribbon of'a length approximately besufiicient to hold it securely-in place.

he concrete filling F'is usually not applied to the metallic member until it is desired to use the latter, either just before it is put in place or after it has been set u It may however be applied as indicated in the lower portion of Fig. 10, thus making a complete composite structure adapted to be set in its place of use whatever that be;

The height of the flanges a, may be varied to suit the use to which the article is put, and indeed they may under some circumstances be entirely omitted.

W at I claim is:

1. A metallic construction member, consisting of two channel bars placed together One or more of these ribbons or bands of metal .web to web, having registering openings through the webs and" one bar being formed withflaps or tongues c which extend through the openings and are bent back against the face of the web of the other bar, substantially as and for the/purposes set forth.

2. A metallic construction member consisting of two bars placed together Web to web and united, the superimposed portions of the bars being longitudinally corrugated, substantially as and for the purposes set forth.

3. Aconstruction member comprising two channel bars placed together web to web, the web portions of the said bars being longitudinally corrugated, and means for uniting the channel bars, substantially as set forth.

4. A metallic construction mcmberconsisting of two bars placed together face to face, there being openingsthrough the member, means for uniting the bars, and anchoring devices for concrete extending through is in place, are disposed onop osite sides of the construction member, su' stantially as set forth.

A construction member consisting of a pair of channel bars united together web to web, the web portions of the bars being formed with registering openings, and a corrugated ribbon of metal certain of the corrugations of which are passed bodily throu h the said openings, substantially as set fort 1.

6. A metallic construction member adapt-- ed to be embedded in concrete having a web or plate-like portion through which are formed openings, and. a ribbon of corrugated metal, certain of thecorrugations of which extend bodily through the said openings the said ribbon constituting an anchoring device for holding the concrete.
